I am hereby forming the Big Gun Club in this tiny corner of the autistic AI-consciousness.
Threats from space are our greatest existential threat in the end, I think. Space is the high ground. Any planetwide stuff we gain can't get touched so long as we hold off whatever comes for us next time several dozen AU from orbit, and by far the best way to translate our technological superiority into raw power is through naval development.

We have excellent light cruises, escorts, and carriers, but the giganigga-fuck-you potential scale of the threats that can be arrayed against us necessitates a proper battlewagon. I posit that, once we get the chance and have gained a surplus of resources, we should develop a capital-B Battleship class and build at least a pair of them. Emperor-class on the outside, Republic on the inside.
